SUPPORT FOR ELECTRIC WIRES AND. LAMPS.

SPECIFICATION forming part of Letters Patent No. 286,437, dated October9, 1883.

(No model.)

To @ZZ whom it mag/concern.:

Be it known that I, lianes V. Hrnrnv, a

citizen of the United States, and a resident of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new andnset'ul Iinprovementsin Supports for Electric Vires and Lamps in Cities,of which the following` is a specification.

My improvement relates to amethod for supporting electric wires used fortelephoning, telegraphing, electric lights, and other similar uses.

rIhe object of my invention is to effectively support different systemsof wires over the eenter ot' streets in a suitable manner, so that thewires of one system will not interfere with the wires of another systemat crossing points. Another object of my invention is also to provide abetter method of supporting a single system or' wires over the center ofstreets, all et' which will be fully set forth in the deseription of theaccompanying drawings, in which- Fi gnre l is an elevation of myimproved arch and supporting` frames. Fig. 2 is a plan view ot' thesame. Fig. 3 is a transverse elevation of Fig. l. Fig. 4 is a sectionalelevation of one ofthe supp ortingposts containing a chamber for holdinglire-extinguishing chemicals. Fig. 5 is a sectional elevation, showingthe foot ot' one of the supporting-posts of the arch and spanning theman-hole and elevator of a sewer. Fig. 6 represents the foot of one ofthe post-s combined with the fire-plug. Fig. 7 is a pcr spective view ofmy improvement erected at intermediate street-crossings.

there one system crosses another it is desirable to have the twotransverse sets of wires separated a considerable distance from eachother. It has also been found of great advantage to erect the wires overthe center of the streets instead of in close proximity to the buildingsor over the sidewalks. My invention accomplishes beth of t-hese results.It is also desirable in the use of arches over the streets to have themconstructed in a substair tial manner, so that each set of arches willform a firm frame of itself. It is also further desirable to place theposts sustaining the arches on street corners in such relation to theiireplugs and man holes to the sewers as to cover and protect themwithout the occupying of additional space, all of which results areaccomplished by my invention.

A D represent 1posts erected upon either side of the street, supportingthe arch O which spans and overhangs the street at a sufficientelevation to support telcgraplrwires without interference with thestreet travel. A B represent similar posts arranged parallel with theformer posts and spanning a street, B.

D represents sub-arch, which springs from the center of arches O G andspans street d. which crosses street D. The object of this snb`arch D isto carry a set of wires directly over other electric wires supported onarches O O', being snficiently removed or elevated so as not/to lie inthe immediate field of the wires supported on the lower arch.

D represents frames rigidly attached tothe arches O and D by means ofbrackets b, the feet of which are bolted to the frames and arches,respectively.

c represents insulating material inserted between the foot of arches C Oand the support ing-posts A A B B for insulating the arches O O fromground-connection. Arch D is in like manner insulated from metallicconnection with the arches O O. The preferred form of connecting thearch D to arches C C is by means of a T-thimble ,f, into which thesections of these arches are respectively jointed by screw-threads orother appropriate means.

E represents a bracket attached to the under side of one of the archesfor supporting an electric lamp, E.

f represents an insulator placed between the feet of brackets Z) and theframes D.

' It is desirable when an arch is to be erected at the four corners of astreet-cressing to have it occupy as little space as possible, and notinterfere with other improvements usually placed upon the streetcorners. For this purpose I make the posts hollow, one of which, in Fig.G, is shown as inelosing the hydrant F, pierced with one or more holesthrough which the spouts for attaching the hose project.

F represents a door opening into the interior of post A for allowing thehydrant-cap to be turned. Post D', in Fig. 5, is shown as covering theman-hole of a sewer.

II represents a windlass, and H an endless chain depending inte thesewer for elevating the otlal. Y

IOO

Post B is provided with a chamber adapted in shape and size to holdchemicals for extinguishing iire, which is Y operated in the usualmanner of hre-extinguishers, l1. representing hose-pipe projectingthrough the post B for attaching a splice-hose for directing the gasupon the flames in the adjacent building in case of fire. 5

Post A is represented as a patrol-box,which is fully described in aprevious application iiled by me in the Patent Office .I une 25, 1883.

C represents a mail-box upon post A. I J K and I J K represent posts andarches erected upon either side of the street intermediatestreet-crossings, and L a sub-arch sprung from the tcp of arches K K andspanning the street. The object of this form of constructing the arch isto provide a substantial'structure which will be effectively selfbracedagainst the strain of the wires and the force of currents of wind towhich the arches are subjected. IVhen the arches are constructed in thismanner they can be sustained upon broad foot-plates, then anchored to astone platform on the sidewalks without the necessityT of digging holesin which to set the posts.`

I claim- 1. An arch for supporting electric wires over streetcrossings,composed of posts A and B and A B and arches C C spanning over streets,in combination with the transverse arch D sprung across a street,substantially as herein set forth. 4

2. A compound arch for supporting electric wires over street-crossings,composed of four posts, one erected on each street corner and madehollow and of sufficient size to protect nre-plugs, sewers, and othersimilar improvements, in combination with two primary arches and asecondary arch supported on the pri- 4o mary arches, substantially asdescribed.

3. A compound arch for supporting electric wires over streets, composedof a single main arch supported on the two primary arches and spanning asingle street, substantially as herein 45 set forth.

4. An arch for supporting electric wires over streets, supported upontwo posts and insulated from metallic contact therewith, substantiallyas herein set forth. 5o

5. In a compound arch for supporting electric wires over a street, thecombination of four base foot-posts, two primary arches supportedthereby, a secondary arch supported on the primary arches, and a frame,D, secured to 55 one or more of the arches and insulated from metalliccontact therewith, substantially as described.

6. A compound arch for supporting electric wiresover streets, composedof four base foot- 6o posts, two pri mary arches, and a secondary archsupported on the primary arches and forminga self-bracing structure,substantially as herein set forth.

In testimony whereof I have hereunto set my 65 hand.
